Run the app (Using Teams Toolkit for Visual Studio)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio.

  1. Install Visual Studio 2022 Version 17.10 Preview 4 or higher Visual Studio
  2. Install Teams Toolkit for Visual Studio Teams Toolkit extension
  3. In the debug dropdown menu of Visual Studio, select Dev Tunnels > Create A Tunnel (set authentication type to Public) or select an existing public dev tunnel.
  4. In the debug dropdown menu of Visual Studio, select default startup project > Microsoft Teams (browser)
  5. In Visual Studio, right-click your TeamsApp project and Select Teams Toolkit > Prepare Teams App Dependencies
  6. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps.
  7. Select Debug > Start Debugging or F5 to run the menu in Visual Studio.
  8. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

  1. Setup Ngrok

  • Run ngrok - point to port 3978

    ngrok http 3978 --host-header="localhost:3978"

    Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

    devtunnel host -p 3978 --allow-anonymous
